Question for ya all....

My Titan keeps causing my PSU's modular power connectors to eventually melt after like months and months of steady use. I think it may be because of crappy modular cable connectors n connections to the PSU.
The titan side of things - including the Y adapters remain in good shape.
By the way, when you melt the connector to the point where the board burns it's a bitch on wheels to fix.

Melting is caused by a couple of things. When you plug a miner in while the power is on, there is a little spark that happens because the miner's 12 volt caps are charging up from zero. Each spark leaves a nice pock mark on the plug or socket. Eventually that causes resistance which causes heat which causes more resistance.

The other issue is voltage. The cube is going to take a certain number of watts. When you start lowering th voltage below 12v due to cheap cabling, the current draw has to go up. Current is what generates heat in voltage drop situations (P=IE), so when you voltage drops to 10v the thing is now dropping 2v*20a=40w of heat along that line. Then it gets hotter resistance goes up, hilarity ensues.

Third thing is the interconnections between the PCIe connector and the Titan board, if you look at the ground lines on layer 1 and 6 you see that the PCIe pin goes to a via which connects to a very small set of four spider connectors to the ground plane. They do the same thing with +12, it's only a few mm, but as you heat up those pins you will start to burn out those spiders. Once one pin's spiders go the other spiders have to carry more of the load which burns those pins and you know where this leads.

Solution? You could run a supply with a massive amount of power, but remember those cubes don't have fuses in them so if something like a FET shorts inside a power supply you go from a simple *pop* to what could nicely be described as a small plasma fireball (see Amp Interrupt rating). This can then cause the phenolic on the board itself to conduct which will turn your unit into a 3,000 watt electric dryer in a 1 foot cube. This could then be described as "hilarious".

Or try dropping down the power. These units hash nicely at 60mh, do you really need 80+?

Sad  Cry . We honestly do not in retrospect

wait for it.....    Wait for It............  WAIT FOR IT......................

RELEASE of GenTarkin's Mod ~ Custom KNC Titan Firmware v1.0.0 IS FINALLY HERE!!!!!!!!!!!!

Previous customers: head to http://gentarkincustomtitan.pcriot.com/custom-knc-titan-firmware-myaccount/ to obtain your FREE UPGRADE and license key(s)!!

New / Unverified previous customers: head to http://gentarkincustomtitan.pcriot.com/custom-knc-titan-firmware-shop/ to purchase!!

RELEASE NOTES:

Major Features, Additions, Fixes & Changes:
Added the long awaited “Energy Saver” feature – automatically tunes die voltages for highest effeciency while keeping the die stable as possible & hw% low. ~~MORE INFO http://gentarkincustomtitan.pcriot.com/energy-saver-faq-help/ ~~
DCDC Over-Current protection – any DCDC’s detected above 46A will be issued a die reset, if that fails then die speed is clocked down significantly to prevent DCDC failure.
Long Term Stability checking for all dies – bumps voltage up on a die if it becomes unstable more than 2x in a period of 2 days.
Per RPI Cube Tracking – if cubes are added, removed or moved around their last known clocks and volts on a given pi will be restored.
Internet outtage / dead pool detection to prevent miner from constantly resetting itself.
Slight webgui redesign.
Product license activation.
Full Copyright & end user license information.
Much smaller installation file.


Additional Features, Additions, Fixes & Changes:
Full translation of webgui pages to 80+ different languages.
Logging file output format refined and also includes more timestamps now.
Optimized timing of die / cube soft and hard resets.
Fixed format of advanced.conf file not being updated properly when user changes/removes/adds cubes or manually sets dies OFF.
ADVANCED page now shows which dies(if any) are being throttled because of DCDC over temp threshold.
ADVANCED page now auto refreshes every 5 minutes.
Noticed in rare cases dies are configured with positive voltage – wrote correction code for this.
For “Energy Saver” implemented cross reboots internal data array tracking capability.
Ability for user to save Log Files to a file to be posted or emailed for diagnostic purposes. (This is part of the Energy Saver options).
Added BALANCE strategy to MINER page – this may work better than LOAD-BALANCE for some users.
Removal of BFGminer version option – in testing 5.1.0 works best with Titans – can re-add later on as an optional installation file if demand is high enough.
More fixes to KNC’s shoddy code.
And many more small fixes / improvements too numerous to list.

All the previous firmware features and improvements are included!

Now … you’re probably asking yourself “yeah yeah, but how much do all these wonderful new features cost?” Simple: $75 first full copy, $35 for additional licenses.

Verified Previous Customers: The upgrade to this firmware is completely FREE for the number of Titans the previous version was purchased. Additional Titans require additional license purchase. If you created an account here previously then you will find license keys issued to your account. **NOTE** If you have not created an account on this site and verified your previous purchases, please contact me - http://gentarkincustomtitan.pcriot.com/custom-knc-titan-firmware-contact/
--
New Customers: Prices as detailed above.

***IMPORTANT INSTALLATION NOTICE*** – Upon upgrading to and activation of this firmware, its EXTREMELY IMPORTANT to keep track of which license was used on your KNC Titan(s). An easy way to do this is create backups of your Titan(s) after activating, then keep record of which backup went to which Titan.

***PRODUCT NOTICE*** – upon purchasing / obtaining this software, the end user agrees to the license terms set forth here(this file is also contained in my firmware): gentarkincustomtitan.pcriot.com/gentarkin_mod/LICENSE








FOLLOWUP REMINDER .... gentarkincustomtitan.pcriot.com is currently the ONLY VALID SOURCE of my firmware.

All others are fake clones based on outdated and extremely buggy code.

Going through auto tune now at stage 2 of 3, so far so good. Power usage seems down a bit, but will know after it finishes.

Describe mumbling....
The die pulls power, but throws errors from time to time on the die that shuts down either the die or the die next to it as well. Fixed by cycling the miner, but then it comes back. Sometimes you see the current on the supplies drop to zero.

I don't have a unit now that does this, but did awhile back.

Other annoyances include dies that hash fine for awhile, then the supplies drop to zero. Rebooting the cube fixes it, sometimes dropping the supplies to zero does so as well. Also an odd one, I had a unit that once had a power supply simply disappear. Because I was running it at 200mhz the other supply handled the load fine but it was odd.

These are the days of our lives. :-)

If its not due to a hardware failure then this is one of the things my firmware has automated from day 1 - handling "sleeping dies" or as you put it "mumbling dies"

Hardware failure is one of those really hilarious terms in Titan-land. I'll have to grab a copy over the weekend, hopefully you take... bitcoin? Or maybe that litestuff? :-)

On an un-related note I figured out how to fix wedged Neptune/beaglebones, fix dead display devices (hint the KNC soldering job sucks), and now that I have a spare am fiddling with the concept of how to run the titan firmware. FPGAs are up and running, just need to tweak the titan driver in bfgminer....

Never dull.

so theoretically, with a bit of rummaging - one might turn a neptune doorstop into a 'fully'-functioning titan??

very interesting.... im fully powered down now & have a considerable amount of expensive junk just gathering dust.

i asked our local scrap merchant how much he'd pay for a fully functional Ant S2 (with working PSU) - $1.70 USD.

so all my obsolete shit is sitting, waiting for the day they have some purpose


what are you making per cube per day/month?

I assume one could run 3-5 cubes from a single controller board (+ extras)


zzz - exhausted just typing that

If you can get a Titan processing board, sure. The controller baseboard for the Neptune, Titan, and Jupiters are identical, the Titan uses a Raspberry pi plus a bridgeboard but I'm whacking away at getting a modern beaglebone running. The trick is figuring out how to remap the gpio ports, but I'm working on it. Unix lets you pull all sorts of funny crap.

Myself, I am not mining so much as fixing other people's stuff. The titans are worth fixing at this point, good systems.

Posting a Titan firmware for the Beaglebone soon, works for all KNC miners Jupiter, Neptune, and Titan.... Keep an eye out in the next few days...

Aw damn, you're going to beat me to it. The key for me was realizing that the fpga-titan code can be loaded with the neptune fpga loader and the io-pwr command from the neptunes.

Couple that with compiling up the driver support code with a few hacks into bfgminer and you're up and running.

Nice job, thanks for working on this. Now I have more time time fix hardware fails.

ah..crap.....


was gonna take my Jupiter 4 port beaglebone apart and try the old pi/titan clone bridge(thanks qwberty) and my 4 port jupiter card)

hell

I suppose I should just wait a couple days huh?


posted this here and sent you a pm on this if you want me to test such ...BEFORE I hack it apart in the other method

as I look at my 4 port Oct jupiter card with bbb still attached......(so close to dismemberment baby) Smiley

anyway seems I got's options! Smiley

Well an aside...in that I installed the new TarkyTitan firmware 1.0.0 without incident. (wow...evil miners tamed so far) Smiley

Anyway....the instructions said NOT to throttle back dies..thus 2 dies I had on 1 cube that were set to 225 and 200 I set back 300 and -0.0366 volts (default).

I left the problem cubes 3 dies off (got it that way) and its one working die at 325 mh. Had one cube I have not tried at 325 mh because it mines at -0.0766 or
some such 'ridiculous' low voltage so it is at that at 300mh. Last cube I left at 325 full out at -0.0366 (default voltage)


So should I have set those 2 low end 200's range dies back or not? Should I have set all for 300mh standard voltage that works or not?

Anyway ...I'm in the process now of it trying to figure out my 2nd Titan setup......so if the above plays out and did not work because of my 'tweaking'

let me know....I should have.....sigh.....asked on here first probably before just going with above...but if I was incorrect just lost a bit of time I guess and a redo

thanks for the software ...we all appreciate it Smiley


Edited

Restarted dies at 200 and 225 the default did not fly I used above


For those not yet pop'ing this up yet. I guess I will find out if it ups my set die speed

Doubt it...

Been chugging along for 1hr or so
